Specific Embodiments

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

[0021] Please refer to Figures 1 to 4, the present utility model provides a technical solution: an adjusting structure, including a base 1. The base 1 includes a base plate 101, and four connecting holes 102 distributed in a rectangle are formed on the upper surface of the base plate 101. Two opposite vertical rods 103 are fixedly installed on the upper surface of the base plate 101. A connecting insertion tube 2 is arranged between the two vertical rods 103. Both outer walls of the connecting insertion tube 2 are rotatably connected to the two vertical rods 103 through a first rotating shaft 104. One end of one first rotating shaft 104 extends to the other side of the corresponding vertical rod 103 and is fixedly sleeved with a worm gear 105. The worm gear 105 is meshed and connected with a worm 106 on one side. The worm 106 is rotatably installed on a mounting bracket 107 integrally arranged on the corresponding vertical rod 103.

[0022] Please refer to Figure 1 and Figure 2 , a bubble level is fixedly installed on one outer wall of the connecting insertion tube 2.

[0023] By arranging a bubble level (not shown in the figure) on the outer wall of the connecting insertion tube 2, it is convenient for the user to observe whether the whole connecting insertion tube 2 is in a vertical state, so as to provide a relatively stable support and connection for the vertical frame of the scaffolding, and improve the stability during use.

[0024] Please refer to Figure 3 and Figure 4 , auxiliary support and limit assemblies 3 are arranged at both ends of the base 1. Each auxiliary support and limit assembly 3 includes an arc-shaped limiting member 301. The arc-shaped limiting member 301 is arranged at one end of a telescopic mechanism. The telescopic mechanism is rotatably connected to a lifting mechanism.

[0025] The two arc-shaped limiting members 301 can limit and support the connecting insertion tube 2 from both sides, so as to share the force to improve the limit stability and service life. The height of the arc-shaped limiting member 301 can be adjusted through the corresponding lifting mechanism. Through the corresponding telescopic mechanism, the two arc-shaped limiting members 301 can be telescoped following the rotation of the connecting insertion tube 2, so as to always fit on the outer wall of the connecting insertion tube 2 to support and limit it. According to the angle and force direction of the connecting insertion tube 2, the two arc-shaped limiting members 301 are located at the two ends on both sides of the connecting insertion tube 2, avoiding further rotation of the connecting insertion tube 2 along the force direction, improving the stability during use and sharing the force to reduce the wear between the worm 106 and the worm gear 105.

[0026] Further, the lifting mechanism includes two extension plates 302 and a bidirectional screw 312. The two extension plates 302 are respectively fixedly connected to the outer walls on both sides of the same end of the base plate 101. Vertical plates are integrally provided at the ends of the two extension plates 302 away from the base plate 101. The bidirectional screw 312 is rotatably connected between the two vertical plates. A chute 303 is formed on one side surface of each extension plate 302. A slider 304 is slidably connected in each chute 303. Threaded holes are formed on one side surfaces of the two sliders 304, and the two sliders 304 are simultaneously threadedly connected to both ends of the bidirectional screw 312 through the threaded holes. One end of a connecting rod 305 is rotatably connected to the top of each slider 304. The other ends of the two connecting rods 305 are rotatably connected to the telescopic mechanism.

[0027] Since the two sliders 304 are simultaneously threadedly connected to both ends of the bidirectional screw 312 through the threaded holes and are simultaneously slidably connected to the corresponding extension plates 302, when the bidirectional screw 312 is rotated, the two sliders 304 will perform synchronous reverse sliding displacements, thereby driving the displacement of one end of the two connecting rods 305 to cause an angular change to adjust the height of the telescopic mechanism and the arc-shaped limiting member 301. When the angle of the connecting insertion tube 2 is inclined relative to the base 1, the two arc-shaped limiting members 301 are located at the heights of the two ends of the connecting insertion tube 2 to limit the connecting insertion tube 2.

[0028] Further, the telescopic mechanism includes a U-shaped mounting seat 308. One end of a second rotating shaft 307 is rotatably connected to both side surfaces of the U-shaped mounting seat 308. The other end of each second rotating shaft 307 is fixedly connected to a U-shaped hinge seat 306. Each U-shaped hinge seat 306 is rotatably connected to one end of the corresponding connecting rod 305. A threaded hole is also formed at the center position of one inner wall of the U-shaped mounting seat 308. An adjusting screw 309 is threadedly connected in the threaded hole. One end of the adjusting screw 309 is rotatably connected to the outer wall of one side of the arc-shaped limiting member 301. The other end of the adjusting screw 309 is rotatably installed in a through hole formed on one side surface of the mounting plate 310. Two guiding slide rods 311 are arranged in parallel on both sides of the adjusting screw 309. The two guiding slide rods 311 are slidably connected in corresponding slide holes formed on one inner wall of the U-shaped mounting seat 308, and both ends of the two guiding slide rods 311 are respectively fixedly connected to the outer wall of one side of the arc-shaped limiting member 301 and one side surface of the mounting plate 310.

[0029] When rotating the corresponding adjusting screw 309, since the adjusting screw 309 is threadedly connected to the threaded hole formed in the inner wall of one side of the U-shaped mounting base 308, and the U-shaped mounting base 308 is integrally connected between the ends of the two connecting rods 305, the rotation of the adjusting screw 309 can drive the arc-shaped limiting member 301 to displace along the guiding slide rod 311 as the guide, thereby adjusting the distance between the arc-shaped limiting member 301 and the connecting socket 2, so that the two arc-shaped limiting members 301 can always fit the two ends of the connecting socket 2, support and limit the connecting socket 2, avoid further angular deflection of the connecting socket 2 along the direction of the force, and improve the stability of the angular limit.

[0030] Furthermore, an anti-slip rubber pad is provided on the inner wall of the arc-shaped limiting member 301.

[0031] By providing an anti-slip rubber pad inside the arc-shaped limiting member 301, while improving the friction with the connecting socket 2 and enhancing the support stability, it can also protect the outer wall of the connecting socket 2, avoid wear caused by mutual friction, and thus improve the overall service life.

[0032] Furthermore, the inner diameter of the arc-shaped limiting member 301 is the same as the outer diameter of the connecting socket 2.

[0033] The same diameter of the two can ensure the fitting area, thereby enhancing the support stability.

[0034] Working principle: Connect the base plate 101 to the scaffold base through the connecting holes 102, then install the scaffold base on the sloping ground. Rotate the worm 106 to drive the worm wheel 105 to rotate, thereby realizing the independent angular adjustment of the connecting socket 2 relative to the base 1. Observe whether the connecting socket 2 is in the vertical state through the bubble level provided on the outer wall of the connecting socket 2, and then insert the vertical frame of the scaffold into the connecting socket 2 to complete the overall connection with the scaffold and support the scaffold. Due to the self-locking effect of the cooperation between the worm 106 and the worm wheel 105, the stability of the connecting socket 2 when supporting the scaffold is relatively high. At the same time, in order to further improve the stability and reduce the wear between the worm wheel 105 and the worm 106, the arc-shaped limiting members 301 in the two auxiliary support and limit assemblies 3 can be adjusted in position and angle through the corresponding lifting mechanism and telescopic mechanism, so that the two arc-shaped limiting members 301 are located at the two ends on both sides of the connecting socket 2 for support and limit, avoiding further angular rotation of the connecting socket 2 along the overall force direction, thereby improving the structural stability and reducing the wear of the limiting structure.

[0035] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
